Road Test

ROAD TEST [RC4A-EL]

Warning:
^ When performing a road test, be aware of other vehicles, people, impediments to avoid an accident.

Note:
^ When the legal speed limit must be exceeded, use a chassis dynamometer instead of performing a road test.

Road Test Preparation
1. Inspect the engine coolant level.
2. Inspect the engine oil level.
3. Inspect the ATF level. (See Automatic Transmission Fluid (ATF) Inspection [RC4A-El] [RC4A-El] Automatic Transmission/Transaxle
4. Inspect the idle speed and ignition timing in the P position.
5. Wait until the engine and transmission reach normal operating temperature.

Shift Diagram:





D Range Test
1. Perform road test preparation.
2. Shift the selector lever to the D range.
3. Accelerate with the throttle half and then wide open.
4. Verify that 1->2, 2->3, and 3->4 upshifts can be obtained. The shift points must be as shown in the table below.
^ If there is any malfunction, inspect the TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [RC4A-EL].) Symptom Troubleshooting Item Table
5. Drive the vehicle in 4GR, 3GR, and 2GR and verify that kickdown occurs for 4->3, 3->2, 2->1 downshifts, and that the shift points are as shown in the table below.
^ If there is any malfunction, inspect the TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [RC4A-EL].) Symptom Troubleshooting Item Table
6. Decelerate the vehicle and verify that engine braking effect is felt in 2GR, 3GR, and 4GR.
^ If there is any malfunction, inspect the TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [RC4A-EL].) Symptom Troubleshooting Item Table
7. Drive the vehicle and verify that TCC operation is obtained. The operation points must be as shown in the table below.
^ If there is any malfunction, inspect the TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE[RC4A-EL].) Symptom Troubleshooting Item Table

Shift point table

Shift Point Table:





M Range Test
1. Perform road test preparation.
2. Shift the selector lever to M range.
3. Verify that 1->2, 2->3, and 3->4 upshifts and 4->3, 3-->2, and 2-0 downshifts are obtained by manual shifting.
^ If there is any malfunction, inspect the TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE ( RC4A-EL].) Symptom Troubleshooting Item Table
4. Decelerate the vehicle and verify that 4->3, 3->2, and 3->1 downshifts are obtained. The shift points must be as shown in the table below.
^ If there is any malfunction, inspect the TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [RC4A-ELI.) Symptom Troubleshooting Item Table
5. Decelerate the vehicle and verify that engine braking effect is felt in all gears.
^ If there is any malfunction, inspect the TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [RC4A-EL].) Symptom Troubleshooting Item Table
6. Drive the vehicle and verify that TCC operation is obtained in 3GR and 4GR. The operation points must be as shown in the table below.
^ If there is any malfunction, inspect the TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [RC4A-EL].) Symptom Troubleshooting Item Table
7. Drive the vehicle in 4GR, 3GR, and 2GR and verify that kickdown occurs for 4->3 and 3-42 downshifts, and that the shift points are as shown in the table below.
^ If there is any malfunction, inspect the TCM and AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [RC4A-EL].) Symptom Troubleshooting Item Table

Vehicle Speed At Shift Point Table:





P Position Test
1. Shift into the P position on a gentle slope. Release the brake, and verify that the vehicle does not roll. If there is any malfunction, inspect the AT. (See SYMPTOM TROUBLESHOOTING ITEM TABLE [RC4A-EL].) Symptom Troubleshooting Item Table

Incorrect Gear Ratio (Slippage) Test

Note:
^ If a gear ratio is incorrect but is not detected accurately, it will not be output as a DTC. In order to be output, after shifting into each gear position, the gear position must be held while the vehicle is driven at a speed of 10 km/h (6.2 mph) or more for at least 7 s.
^ An incorrect gear ratio refers to a situation in which, due to clutch slippage in the AT, the input and output rotation of the AT differs from a certain value.

1. Perform road test preparation.
2. Perform the following steps.
(1) Shift into the D range (1GR) and drive for 7 s or more.
(2) Shift into the D range (2GR) and drive for 7 s or more.
(3) Shift into the D range (3GR) and drive for 7 s or more.
(4) Shift into the D range (4GR) and drive for 7 s or more.
3. Stop the vehicle.
4. Inspect for a DTC.
^ If any DTC is present, repair according to the inspection procedure for the applicable DTC.
